The predicting role of self-efficacyin the Job Demands-Resources Model: A longitudinal study
2012
AbstractTaking Albert Bandura's Social Cognitive Theory as our starting point, we analysed the predicting role of self-efficacy in the Job Demands-Resources Model. We tested longitudinally the two underlying psychological processes, namely: 1) the motivational process, in which job resources (i.e., job autonomy and social support climate) foster engagement, and 2) the erosion process, in which high job demands (i.e., quantitative overload and role conflict) lead to burnout. Structural equation modelling in a sample of 274 secondary-school teachers confirmed both processes, as well as the powerful predicting role of self-efficacy. Finally, we discuss the theoretical findings and the practica…
Customer Loyalty in Clusters: Perceived Value and Satisfaction as Antecedents
2009
Purpose: This paper studies, from the perspective of relationship marketing, the loyalty behavior of industrial customers in the context of a cluster. Loyalty is a key variable for studying long term relationships between firms. Research implications: Recent advances in consumer and services marketing consider that perceived value and satisfaction are central to explaining customer loyalty. However, very few studies in B2B explain the antecedents of customer loyalty. This study adopts the relationship marketing approach, and loyalty behavior is being analyzed in a specific setting: an industrial cluster. Furthermore, the effect of the number of suppliers is analyzed as a possible moderator …
Analysis of Spatial Disparities by a Structural Equations Model
2008
This paper presents a new analytical framework for assessing spatial disparities among countries. It takes for granted that the analysis of a country’s performance cannot be limited solely to either economic or social factors. The aim of the paper is to combine relevant economic and non-economic (mainly social) aspects of a country’s performance in an integrated logical framework. Based on this idea, a structural simultaneous equation model will be presented and estimated in order to explore the direction of the causal relationship between the economic and the non-economic aspects of a country’s performance. Furthermore, an exploration of the trajectory that each country has registered over…
Interindividual Differences in Treatment Effects based on Structural Equation Models with Latent Variables: An EffectLiteR Tutorial
2019
The investigation of interindividual differences in the effects of a treatment is challenging, because many constructs-of-interest in psychological research such as depression or anxiety are latent variables and modeling heterogeneity in treatment effects requires interactions and potentially nonlinear relationships. In this paper, we present a tutorial of the EffectLiteR approach (Mayer, Dietzfelbinger, Rosseel, & Steyer, 2016) that allows for estimating individual treatment effects based on latent variable models. We describe step by step how to apply the approach using the EffectLiteR software package with data from the multicenter randomized controlled trial of the Social Phobia…
The Influence of Parents on Achievement Orientation and Motivation for Sport of Adolescent Athletes with and without Disabilities
2011
The purpose was three-fold. First, to analyze the psychometric properties of scales used. Second, to test the relationship among athletes’ perceptions of parents’ goal orientation and their own goal orientation and intrinsic motivation. Third, to compare athletes with and without disabilities with respect to the influence of parents on athletes’ achievement orientation and motivation for sport. Participants were 173 amateur athletes (80 with disabilities, 93 without disabilities). Structural equation models revealed that for the athletes with disabilities, task orientation and the perceptions of parents’ task orientation were related to athletes’ interestenjoyment and effort-importance. For…
Bidirectional longitudinal relations between father-child relationships and Chinese children's social competence during early childhood
2013
Abstract Using a two-year and three-wave cross-lagged design with a sample of 118 Chinese preschoolers, the present study examined bidirectional longitudinal relations between father–child relationships and children's social competence. The results of structural equation modeling showed bidirectional effects between father–child conflict and social competence. Higher conflict in father–child relationships at three months after preschool entry predicted lower levels of children's social competence at the end of the first preschool year over and above continuity in competence. Lower levels of social competence at three months after preschool entry also predicted higher father–child conflict a…
Media Attention and Radical Right-Wing Populist Party Sympathy: Longitudinal Evidence From The Netherlands
2018
Contains fulltext : 201972.pdf (Publisher’s version ) (Closed access) This contribution provides evidence for the sources of sympathies for radical right-wing populist (RRP) parties in a longitudinal perspective. We extend previous knowledge by evaluating the impact of media attention on individual changes of RRP party sympathies. To test our hypotheses, we use panel data from The Netherlands and combine it with information on the saliency of RRP parties and their issues in major Dutch newspapers. Drawing on multilevel structural equation models, our findings indicate that media attention positively affects changes in RRP party sympathies. Furthermore, we find that the effect of media atten…
Relationships Between Ethnic Identity, Ethnic Attitudes, and Acculturative Stress in Tunisian Individuals in Early and Middle Adolescence
2016
Framed from an integrative approach, the current article examined the associations between ethnic identity exploration (EIE), ethnic identity commitment (EIC), and acculturative stress by investigating the mediating role of ethnic attitudes (i.e., in-group favoritism and out-group derogation) in these relationships. Additionally, the moderating role of age was analyzed. A multiple-group path analysis was performed on data collected from 256 Tunisians in early and 248 in middle adolescence living in Italy, which is an interesting and understudied immigrant group characterized by similarities and differences with the host population. In younger adolescents, EIE and EIC were indirectly and po…
Artificial Vision and Soft Computing
1999
The term soft-computing has been introduced by Zadeh in 1994. Soft-computing provides an appropriate paradigm to program malleable and smooth concepts. For example, it can be used to introduce flexibility in artificial systems to improve their Intelligent Quotient. The aim of this paper is to describe the applicability of soft-computing to artificial vision problems. Good performance of this approach is assured by the fact that digital images are examples of fuzzy entities, where shapes are not always describable by exact equations and their approximation can be very complex.
Saturation excess runoff numerical simulation
2005
Saturation excess runoff is a relevant process which needs additional experimental and modeling efforts. This work is focused on its numerical modeling. The final objective is the successive interpretation of ongoing experimental monitoring results in two watersheds in different areas of Italy where the saturation excess runoff formation mechanism seems to be important. The numerical solution of the two-dimensional Richards’ equation allows the evaluation of the sensitivity to the various influent parameters : rainfall intensity, soil properties, depth and initial water content, slope and hillslope length. Also the subsurface flow is simulated at the same time, allowing the evaluation of th…
